Update, October 9, 2026: ATF no longer requires a Form 4, tax stamp, fingerprints or registration for suppressors, short-barreled rifles, short-barreled shotguns or AOWs. They now transfer on a standard Form 4473 with a background check. Anything below that mentions a Form 4, a wait or a tax stamp was written before this change. What changed
The Colt’s Manufacturing M5 Semi-Auto Rifle is a semi-automatic rifle with a 14.5″ barrel and a 30+1 capacity. It carries the Colt name and the model number CM556-14H-M5S, which is the number to use when you compare listings or talk to your transfer dealer.
The two numbers that define this rifle are the barrel length and the capacity. The 14.5″ barrel sets its overall feel. The 30+1 capacity means 30 in the magazine and one in the chamber, so you can run longer strings before a reload.
Who it suits
This rifle fits shooters who want a semi-auto Colt for the range, for training classes or for home defense planning. It also suits collectors who like to own current Colt production. If you already shoot a Colt, the name and model will be familiar.
Plan your gear around how you will use it. A sling makes carrying easier. A good optic or sights, extra magazines, a padded rifle case, ear and eye protection and a cleaning kit all pair well with a rifle like this. Check that any accessory you pick matches the rifle’s own mounting and fit before you order.
